CENTERING- CH'UUK FOR WEB ROLLS.

' Application filed March 19, 1925.

This invention relates to a device for supporting and centering theendof a web roll in position to feed the web to a newspaper printingpress. 1

The principal objects of the invention are to provide means forsupporting each end 01" the web roll from a pair of centers in a firmmanner so that the web can be taken from the roll in the usual way andwhen exhausted the roll can be removed expeditiously by a very'simplemovement of the supporting spindle and the mounting of the roll will becorrespondingly facilitated. The invention also involves means foreliminating all ferrules within the spools and reducing friction.

Other objects and advantages of the in vention will appear hereinafter.

Reference is to be had to the acco1npanying drawings, in which Fig. 1 isa side view of a reel provided with a preferred embodiment of this invention showing it in operative position;

Fig. 2 is a fragmentary view of one end of the reel showing the way ofdismounting the spool of the exhausted roll; and

3 is an end view or the reel.

This invention is intended to be used with the reel comprising a shaft10 and spiders 11 for supporting a plurality of web rolls R in a paperfeeding device for a newspaper printing press. The spiders are formedwith whatever number of arms is required to support the desired numberof rolls around the shaft 10. It will be understood that the shaft 10 isturned from time to time to bring a new roll up to web deliveringposition and to permit the core or spool oi the old roll to be removedat another point, as is usual in this art.

Each of the arms of the spider at one end of the reel is provided with anon-reciproc-able steel spindle 12 fixed to each arm by a split collar13. This spindle has a convex, and preferably conical, center 14 forreceiving the roll at one end.

At the other end of the reel the corresponding arms are provided withhollow bearings 15 in which are mounted reciprocable spindles 16provided with conical centers 17 corresponding with the centers 1 1previously described. Each of these latter spindles is provided with arack 18 or the like with which meshes a gear or pinion 19 on a shaft 20carried on a bracket 21 fixed to the arm 11. The shaft is provided withSerial No. 16,803.

a handle 22 which can be swung from the full to the dotted'line positionin Fig. 1 for the purpose of reciprocating this spindle to hold orrelease the web roll. it will be understood, of course, that in the formshown I there are three pairs of spindles arranged for the supportofthree web rolls around the shaft 10, although any other convenientnumber can be employed.

For the purpose of supporting the roll it on the conical centers 14 and17 I provide a 27 which is drawn up against the end '01 the web roll;that is, the edges of the paper. In the flange is a conical centraldepression 28 beveled to fit the conical centers 14 and '17. Thesechucks are made of solid pieces of metal or even wood, if desired, andare placed in the ends of the spools of the rolls R- before they areapplied to the reel. The shanks are made to fit tightly in the ends ofthe spools.

In the application of the rolls, one end is lifted and located so thatthe center 1 1 on ters the depression 28 in oneof the chucks located inthe roll. The other end of the roll is raised into substantially levelposition and then the handle 22 is moved over to push the spindle 16toward the roll until the center 17 enters the depression 28 in theother chuck. On account of the construction shown, a forward movement ofthis spindle of only 2 inches is required in an ordinary newspaperprinting press. To remove the spool of the exhausted roll the spindle 16is drawn back by means 01": the rack and lever. This releases the rolland it can be removed very readily as can be seen. In this way the rollis very quickly applied and detached and no ferrules are required insidethe spools. This results in economy in use.

As these so-called chucks have cylindrical shanks of considerable lengthwhich enter the spool on which the roll is wound, they support the rollfirmly at each end and pre vent its getting out of center although theydo not extend through the roll and are not connected in any way witheach other except by the spool in which they fit tightly. Thus,

they constitute a firm and rigid support. In unwinding of the web, they01"- course rotate with it on the centers 14: and 17.

Although I have illustrated and described only a single form of theinvention I am aware of the fact that modifications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claims. There fore I do not wish to belimited in these respects but what I do claim is 1. As an article ofmanufacture, a chuck for rigidly supporting the end of a web roll for anewspaper printing press comprising a shank of material length adaptedto enter the spool of the web roll and provide with a central depressionfor receiving a pointed supporting center and with means limiting theextent to which the chuck will extend within the spool.

2. As an article of manufacture, achuck tor rigidly supporting the endof a web roll pression for receiving a conical supporting center.

3. A supporting means for a web roll comprising ,a pair of chucks eachhaving a cylindrical shank of considerable length adapted to be fittedinto the end of the spool on which the web roll is wound, each having aflange at the end engaging the end of the web roll, and each beingprovided with a central depression on the outer end for re ceiving asupporting center on which the two chucks can be rotated with the webroll in the unwinding thereof.

l. In a web roll support, the combination of a reel having pairs of armsrotatable therewith, a stationary conical center mounted on each arm atone end of the reel, a reciprocable conical center mounted on each armat the other end of the reel, said centers being in axial alignment,means for reciproeating the movable centers independently oi each other,a pair of chucks for directly supporting each web roll, each chuckhaving depression in the end for receiving the two centers and eachhaving a material portion of a cylindrical form extending into the endof the web roll for supporting the web roll at its ends and carrying iton said centers and means limiting the extent to which the chuck willextend within the roll.

In testimony whereof I have hereunto affixed my signature.
